To all whom it may concern: I

Be it known that I, CLARENCE H. WALKER, a citizen of the United States, residing at New York, in thecounty of New York and State of New York, formerly v of Bur lingame, in the county of San Mateo and State of California, have invented new and useful Improvements in Attachments for Levers, of which the following is a specification.

tary type of transmission, it is necessary when running in low speed to maintain pressure on a lever usually a foot pedal, in order tomaintain the pro er transmission element in engagement. his is particularly true in the Ford make of vehicles, and when traveling any great distance in low speed, such as in congested traffic, or in ascending a long hill, it is very tiresome for the operator to maintain the continued pressure on the low speed pedal or lever.

The present invention relates to an attachment for the transmission controlling pedals or levers of motor vehicles, by the employment of which the operator is re- 'lieved from maintaining tension on the pedal when it is desired to retain the same in its depressed position to enable the, vehicle to operate in one of its lower speeds.

The invention has for its principal objects to provide a construction designed to be readily attached to a pedal of the Ford type without in any Way changing the pedal or mutilating the same and without the aid of a mechanic; one which is capable of op eration by the movementof the foot over the pedal to throw the retaining pawl in operative position to hold the pedal in its operative or depressed position, and one which is designed to be attached without In. motor vehicles employing the plane-.

Specification of Reissued Letters Patent. Rissued Aug. 31," 1920- 917. Application or sacrificing anyof the advantages of the invention. e

To more fully comprehend the invention, reference is directed to the accompanying drawings, Wherein- Figure 1 is a view in side elevation of the preferred embodiment of myinvention applied to the clutch or low speed pedal of a Ford automobile. v

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1, viewed inthe direction of thearrows.

' F ig. 3 is a detailed sectional view taken on line 3.3 of Fig. 1, viewed in the direction of the arrows.

Referring more particularly to the several" views of the drawings wherein like characters of reference designate corresponding parts-1 illustrates the usual transmission cover of a Ford automobile andfrom one side of which projects the brake pedal shaft 2, the reverse speed shaft 3, and the low speed or commonly termed clutch shaft 4, .to which is attached the clutch pedal.5 having the foot engaging face 6. To the shafts 2 and 3 are attached suitable operating levers 7 and 8.

Around the upper portion of the clutch pedal 5 belowthe face 6 is positioned the clamp 9 preferably formed of spring metal and the ends 9 and 10 of said clamp are so disposed as to lie parallel to and in contact with each other, as in Fig. 3, when the clamp is positioned on the pedal, as in the drawings. The end 9 of the clamp is bent laterally at right angles outwardly to the exposed face thereof, said laterally extended portion providing a guide lip 12 which is formed with a guide opening 13. A suitable bolt 13"'passes through alined openings in the ends 9' and 10 of the. clamp, and said bolt retains the clamp in position on the pedal. A suitable clamp comprising the spaced members 14 and 15 retained together by bolts 16, is d eta'chably secured tothe lower portion of the clutch pedal shank and from the member 14 extends the bearing 17 which pivot-ally mounts the pawl 18 formed with the downwardly disposed engaging tongue 19. The free end of the pawl is provided with an eye 20 through which extends the curved lower end of a controlling rod 21 disposed upwardly and passes through the guide opening 13 with its upper end terminating at the rear of the en gaging face 6 at a point slightly-above the rear edge of the same, as in Fig. 110i the drawings. The pawl is normally retained in its raised or inoperative position by aspring 22 coiled about the upper end of the controlling rod 21 and interposed between the lip 12 and a suitable washer 23 limited in its movement longitudinally of therod by a cotter pin 24. l

-- The pawl co" erates with a suitable ratchet 25 tonne in the upper end of a br-acl ret 26. The bracket provided with the legs or supports 27 terminating at their lower ends in the offset feet/28, each provided a bolt opening, the openings being adapted to register with the regular bolt openings in the side flange of the transmission cover and be secured in position by the usual bolts utilized to attach the transmission cover towthe lower half of the motor crank case.

lVhen it is desired to operate the vehicle under the low speed, it is. only required that the operator press forwardly on the pedal 5 and with the toe depress the controlling rod '21, forcing the tongue 19 into engagementwith the ratchet 25, thereby retaining the pedal in its operative position and en-' abli-n-g the operator to release his .foot from the pedal while the vehicle is being oper- Having thus described the invention, what,

I claim as new and desire to secure byLetters Patent, is; U

1. combination with a spring-pressed foot lever provided with :1 foot engaging surface, a pawl and ratchet mechanism for cotiperating with the said lever, comprising a supporting member ionmed in halves for clamping to the lever below said foot ensurface, a :stud supported by said halves, a ,pawl pivotally supported on said stud, a ratchet with which said pawl co operates, an operating rod pivotally connected at one end with said pawl and extending to point above and to the rear of said foot engaging surface, a member clamped to said leverfabove said supporting member and provided with .a portion bent to form a guide and through which the free end of said rod operates, and a spring cooperating with said rod and pawl for normally maintaining said pawl disengaged from said ratchet. I I 12'. In combination with a spring-pressed leverprovided with a foot engaging surface, locking mechanism for the lever comprising a supporting member formed for connection to the lever below said foot engaging surface, a pawl ivotally supportedby said member, .a rate et with which said pawl cooperates mounted independently of the lever, a pawl-operating element mounted on the leverand operable by the foot on saidengaging surface, and a spring applied to the pawl -to' normally maintain it disengaged from the ratchet.

3. In combination with a spring-pressed lever provided with a foot engaging surface, locking mechanism for the lever comprising a. supporting member formed for connection to the lever below said foot engaging surface, a pawl pivotally supported by said member, a ratchet with which said'pawl cooperates mounted independently of the lever,

a pawlsoperating element mounted on the lever and operable by a toot on said engaging surface, ja guide for said element formed for connection to the lever adjacent the footengaging surface, and a spring applied to the pawl .to normally maintain it disengaged from the ratchet' foot lever provided with a foot engaging surface, "locking mechanism for the lever comprising a supporting member :Eormed for clamping to the lever belowsaid foot engaging'surface, a pawl pivotally supported on said member, a ratchet with which said pawl co'iipera'tes mounted independently of the lever, a pawl-operating element operable by a foot on said engaging surface, a supporting member for said element also formed for clamping to the lever, and a spring applied to the pawl to normally maintain it disengaged from the ratchet.
